pg_tablespace

pg_tablespace

The pg_tablespace system catalog table stores information about the available
tablespaces. Tables can be placed in particular tablespaces to aid administration of disk
layout. Unlike most system catalogs, pg_tablespace is shared across all
databases of a Greenplum system: there is only one copy of
pg_tablespace per system, not one per database.
